This exclusive estate, on the market for the 1st time ever, is situated on a spectacular acre knoll with panoramic views of surrounding hillsides. The home is nestled on a hidden gem--a level circular cul de sac in the heart of Orinda, tucked away off the main street of Diablo View Road and ideal for strolls and bicycle riding. The architect designed residence was custom built by master builder Peter Branagh with bespoke details reflecting the standards of quality workmanship and materials of the prominent interior designer owner. The beautifully landscaped grounds feature flowering gardens, inviting patios, meandering pathways, and ample level area for play, pool site, and sport court. Oversize windows and airy interiors contribute to the sense of tranquility and fluid blending with the natural surroundings. The gated driveway leads to a broad entry court with ample guest parking, under the shade of a magnificent 250-year-old heritage oak. The stunning two story living and dining rooms, flooded with natural light and offering 180 degree views, open to the fabulous wrap-around stone terrace. The primary suite has spa-like bath, fireplace, private balcony, and breathtaking views.
